We report new measurements on laser-assisted molecular
dissociative sequential excitation and ionization spectra of strontium
vapor. A single Nd:YAG pumped dye laser in conjunction with an atomic
beam apparatus have been used to investigate the even parity 5snd
Rydberg series resulting from the 5s5p
resonance level. The relative intensities changes among the 5snd
and
Rydberg series are attributed to the
interactions with the 4d6s
perturbers,
respectively. The interchannel interactions between the 5snd
series and the 4d6s
level and among the 5snd
series and the 4d6s
intruders have
been separately parameterized using the two-channel quantum defect
theory. 32.30.Jc Visible and
