Possibility of magnetic rotation in ⁸⁵Zr

Being a few-body quantum mechanical system, observation of the rotation motion in a spherical atomic nucleus is quite unexpected. Therefore, the observation of rotational-like sequence of magnetic dipole (M1) transitions in weakly deformed nuclei has attracted an immense interest in the nuclear physics since last few decades. To summarise, the semiclassical particle rotor model calculation has been carried out for the magnetic dipole band in ⁸⁵Zr. The calculated B(M1) values are found decreasing as a function of increasing spin. This indicates that the shears mechanism is possibly responsible to generate the higher angular momentum states belonging to the band of present interest. Detailed results obtained from this calculation have been presented
