organic spectroscopy: n-phenethylacetamide base peak ion

[Mimic]

This is the n-phenethylacetamide mass spectrum. His base peak ion is at 104 m/z. I have long been thinking about what its structure might be, but with a m/z ratio of 104 I can not think of anything plausible. Can you help me?

Thanks in advance

PubChem has both a classic 2D structural formula and an animated 3D ball and stick picture.

What I would need to know is the base peak ion structure. Is something with 104 m/z ratio
