In order to determine the eigenvalues an d e i g e n f unction w“ a numerical differential scheme h a s b e e n utilized. We seek a solution i n the interval f r o m c e (120) to cg(700). A unique solution exists in this interval an d wi t h e n o u g h p r e cision о-80618,4-259 cm/a. It is w o r t h to note that the function A ( j ) i n (8) is a r bitrary one. It is determined f r o m the c o n dition for solving of the second approach. After exoluding p 2 , p 2 and иг from equations for the seoond approach a spectral problem is obtained) d r [ ^ z , c ) 4 ^ - ] - 4 - ( z , c ) w 2 - (12) w 2 * 0 , z * 120, C g W 2 - gW£ « 0 z - 700 , where , 4, , are functions of z a n d с and t h e y are not presented . r s *и here.
