If the bm1 plot shows less even-odd sttagering pattern. Then what it means in context of physics?

For the odd z nucleus BM1 values shows less odd-even staggering pattern. How can we interpret this in terms of physics and for triaxial nuclei why this pattern should be more pronounced?

While doing calculations on some nuclei, why would I have obtained reduced transition probabilities for some isotopic mass chain of nuclei?

While observing the pattern so obtained for all the isotopes, it is found that B(M1) value for one of the isotope is showing just opposite trend than the rest of isotopes. What would be the reason...

Why don't electrons emit radiations in stationary orbits while revolving around the nucleus?

As we know that, accelerated charged particle radiates energy while moving. why is this not so in the case of electron revolving in the stationary ortbit?

In the reaction where two muons decay to two kaons, which type of interaction is involved?

I think this phenomenon involves a weak interaction, because as in beta decay the parity of the muon is not conserved.

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

How do I determine the degree of polymerization of PEG 400 based on NMR integration?

Hello, I am working on the photocatalytic degradation of PEG 400. I would like to know if it's possible to determine the degree on polymerization based on NMR integration, or by the MW of the...

What is the characteristic length to determine the Reynolds number for the scattered turbulent fluid flow?

Dear all, I just saw this example in FB on the difference between laminar flow and turbulent flow. The flow from a pipe hits the sink and scattered. The flow from the pipe is characterized as...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Why Austenite grains in steel show much more twinning than ferrite grains?

It is oftentimes said to be a distinctive metallographic trait that differentiates a fully austenitic and a fully felly ferritic steel without etching that might distinguish between two. Why...

How Relativistic effects is one reason for lanthanide contraction?

The Lanthanide contraction which is the decrease in ionic radii of the elements in the lanthanide series from atomic number 57, lanthanum, to 71, lutetium, is due to poor shielding of the 4f...

Can someone suggest a way to prepare slides to observe under confocal microscope for observing fluorescent tagged proteins??

I am growing the cells on coverslips and transfecting the fluorescent tagged protein directly on them. Then i want to observe these cells under confocal microscope. Currently i am just using...

What is the most suitable server for predicting protein structures in bacteria?

I have used the i-Tasser several times, however it has been unavailable for several days. I tried the swiss-model, but the output was not very pleasant due to the model used. Is there any other...
