What do you mean by odd odd nuclei?

An atomic nucleus containing an even number of protons and an odd number of neutrons.

How is nuclear spin calculated?

The rules for determining the net spin of a nucleus are as follows; If the number of neutrons plus the number of protons is odd, then the nucleus has a half-integer spin (i.e. 1/2, 3/2, 5/2) If the number of neutrons and the number of protons are both odd, then the nucleus has an integer spin (i.e. 1, 2, 3)

What is nuclear spin quantum number?

In atomic physics, the spin quantum number is a quantum number (designated ms) which describes the intrinsic angular momentum (or spin angular momentum, or simply spin) of an electron or other particle. The name comes from a physical spinning of the electron about an axis, as proposed by Uhlenbeck and Goudsmit.

How is nuclear parity and spin calculated?

The total spin of the nucleus is the (vector) sum of these angular momenta and can take val- ues between |j1 − j2| and |j1 + j2| (in unit steps). The parity is given by (−1)(l1+l2), where l1 and l2 are the orbital angular momenta of the unpaired proton and neutron respectively.

How many odd odd nuclei are there?

Odd mass number (In theory, mass number 143 to 155, 160 to 162, and 165+ can also alpha decay.) This gives a total of 101 stable nuclides with odd mass numbers.

What is odd even effect?

Odd−even effects on structure and property is a widely observed phenomenon in chemistry, physics, biology, and materials sciences. In general, it describes an alternative alteration of materials structures and/or properties depending on the odd or even number of structural units in a molecule.

What do you mean by nuclear spin?

It is common practice to represent the total angular momentum of a nucleus by the symbol I and to call it “nuclear spin”. The nuclear spins for individual protons and neutrons parallels the treatment of electron spin, with spin 1/2 and an associated magnetic moment. …

Which values can a nuclear spin quantum number have?

17.2. When the spin quantum number of a nucleus is non-zero, it possesses a magnetic moment. The proton is such a nucleus. It has a spin I of 1/2 and when placed in a magnetic field of strength B0 it will occupy 2I + 1 quantized magnetic energy states, in this case 2.

What is nuclear spin quantum number of 37cl?

For this band the alternating intensity ratio for the Cl37Cl37 molecule (1.28) was the same, within the experimental error, as for the Cl35Cl35 molecule (1.26), indicating that the nuclear spin of Cl37 is probably also 5/2.
