The predictions of the distorted Fermi-sphere model for magnetic isosc
alar resonances are summarized. In this model a heavy spherical nucleu
s is thought of as a charged piece of spin and isospin saturated nucle
ar Fermi-continuum possessing properties of an elastic-like matter. Th
e magnetic resonances are described in fluid-dynamical terms and inter
preted as manifestations of elastic torsional vibrations of the nucleu
s. The process of nuclear magnetization induced by inelastically scatt
ered electrons is described as a transition from a currentless ground
state to a magnetized excited one which is characterized by a non-zero
magnetic multipole moment. We present calculations of a complete set
of integral characteristic parameters of M lambda, T = 0 resonances su
ch as position of energy peak, excitation probability and magnetic osc
illator strength computed as functions of mass number and multipole de
gree lambda greater than or equal to 2. An analytic form is given for
collective transition current density and the PWBA computed form facto
rs that may be used for analysis of measurements with inelastically sc
attered electrons. Numerical estimates are performed with use of the D
WBA code. Theoretical predictions are presented in juxtaposition with
the DALINAC data available on M2 giant resonance in spherical nuclei.
We briefly discuss the microscopic effects of two-particle correlation
s between nucleons occupying two different single-particle orbits of s
hell structured mean field that may, in our opinion, be responsible fo
r the collective torsional magnetic response predicted by the model in
question.
